[Bf-committers] poll: uv/col mirror might not work for bmesh ngons

[Campbell Barton]

Take care when assuming what people do/dont use in blender :)
this feature was very useful while doing this project.

Often Id have quads around door-frames that needed to be mirrored so
the light would look like it was coming from the outside, since
copying/flipping/mirroring/extruding the faces sometimes would cause
the UVs to be the wrong way around.
